Don’t spoil the soil! Soil-borne pathogen prevention for everyone Created in collaboration with the East Bay Regional Park District Stewardship department and University of California Agricultural and Natural Resources, this 20 minute video focuses on the impacts of soil Phytophthora in wildlands, especially within East Bay natural areas, and how site hygiene can prevent these devastating pathogens from entering new environments.
National Park Service Training
These videos were made possible by the expert knowledge generously provided by Cal-IPC instructors and supporters. Funding was provided by the California Department of Food and Agriculture and the USDA Forest Service, State and Private Forestry, through American Recovery and Reinvestment Act funds. The equipment for filming was provided by the National Park Service’s California Exotic Plant Management Team and the Pacific Coast Science and Learning Center.
